Matthew Hale, a professor at Seton Hall University in New Jersey, told AL.com it’s beneficial for Booker to speak to religious voters, often underserved by Democrats, who are traveling from all over the country for the convention in Mobile.

“That’s a good audience for him. The delegates to the convention come from all over the country, and they will likely return to their home pews with good things to say about Cory Booker,” Hale said.

Hale said Booker's rhetoric is often rooted in language from Christianity and his themes of “conspiracy of love” can “rival the best preachers in the country.”

Booker was one of only a few national politicians who campaigned for Jones last year, the other being Alabama’s lone Democratic Rep. Terri Sewell and former Vice President Joe Biden.

And with Alabama’s earlier primary, it could help his standing among the state’s Democrats should he choose to run for president in 2020.

“On each trip, he is making new friends who will be of great assistance to him before the [Alabama] presidential primary occurs on March 3, 2020,” said William Stewart, professor emeritus of political sciences at the University of Alabama.
